Rubber Mast Chocks

RESPONSIVENESS ~ FROM DESIGN TO DELIVERY™

CR Marine rubber mast chocks are the perfect solution when you need to support an aluminum or carbon fiber mast as it passes through the deck collar. Unlike individual teak mast wedges, CR Marine rubber mast chocks completely encircle the mast to provide an excellent water tight seal between the mast and the deck. One piece gives 360 degrees of support. No more individual wooden wedges that can become loose, fall through and concentrate the load. Graduated steps, tapered to fit most masts, allow the CR Marine rubber mast chocks to fit safely and securely in place with no adhesives. When using CR Marine rubber mast chocks, there's no need to worry about mast wedges shifting out of place.

Available in two sizes, CR Marine rubber mast chocks can easily be cut to size with a hack saw. Using a small amount of caulk with the CR Marine rubber mast chocks can make a water tight seal on most masts.
